The ink is remarkably similar to the hunter green Zebra Sarasa Retractable,
which Jetpens sells. It is cheaper than this pen, writes better, and has a nicer
shade of ink too (the BLX is slightly duller/darker). Overall I've been
disappointed with the quality and colors of all the 207 BLX series except
brown-black, only because I haven't tried it yet.

Love this pen. Writes a smooth clean line with the slightest hint of green.
Writing with it is a pleasure. Without that, nothing else would matter. But
it's also acid-free, water-resistant, fade-resistant, and archival. You can't
beat that. Oh, and for less than two bucks. I mostly prefer fountain pens, but
I carry this around because it weighs hardly anything, I don't have to worry
about losing it, and I can write checks or notes and know they will last and be
secure. What's not to like?
